Daily Current Affair Quiz: 28th April 2020
1. Which of the following statements are true?
1. Israel Institute of Technology have developed a concept named the Ramanujan Machine, after the Indian mathematician.
2. The purpose of the machine is to come up with conjectures in the form of mathematical formulas that we can analyze.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
- Scientists from Technion — Israel Institute of Technology have developed a concept named the Ramanujan Machine, after the Indian mathematician. About Ramanujan Machine
- It is an algorithm that reflects the way Srinivasa Ramanujan worked during his brief life.Throughout his life, Ramanujan came up with novel equations and identities including equations leading to the value of pi and it was usually left to formally trained mathematicians to prove these.
- The purpose of the machine is to come up with conjectures in the form of mathematical formulas that we can analyze.
- In most computer programs, humans input a problem and expect the algorithm to work out a solution. But with the Ramanujan Machine, it works the other way around.
- Feed in a constant, say the well-known pi, and the algorithm will come up with an equation involving an infinite series whose value, it will propose, is exactly pi.
2. TEMPLATES Programme is associated with
(a) How new stars are born
(b) Researching on Moon’s farthest side
(c) Exploring exoplanets
(d) Learning more on gravitational waves
Ans: a
Justification:
- Recently, NASA announced that they plan to investigate how new stars are born. For this, they will take the help of a natural phenomenon called “gravitational lensing”.
- This programme is called TEMPLATES (Targeting Extremely Magnified Panchromatic Lensed Arcs and Their Extended Star Formation).
3. Which of the following statements are true?
1. Common Service Centre is an initiative of Ministry of Electronics & IT.
2. CSCs are the access points for delivery of various electronic services to villages in India.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
- It is an initiative of Ministry of Electronics & IT. CSCs are the access points for delivery of various electronic services to villages in India.
- The CSCs provide high quality and cost-effective video, voice and data content and services, in the areas of e-governance, education, health, telemedicine, entertainment as well as other private services.
- Under CSC 2.0 scheme launched in 2015 seeks to set up at least one CSC in each of the 2.5 lakh GPs across the country by 2019. It forms a part of Digital India programme.
4. Which of the following statement/s is/are true.
1. Gogabeel is an ox-bow lake in Bihar.
2. It is formed from the flow of the rivers Mahananda and Kankhar in the north and the Ganga in the south and east.
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Ans: c
Justification:
- It is an ox-bow lake in Bihar’s Katihar district. It is formed from the flow of the rivers Mahananda and Kankhar in the north and the Ganga in the south and east.
- Among the threatened species, the Lesser Adjutant falls in the vulnerable category; and three species, the Black-necked Stork, White Ibis and White-eyed Pochard are under the near threatened category.
- Other species reported from this site include Black Ibis, Ashy Swallow Shrike, Jungle Babbler, Bank Myna, Red Munia, Northern Lapwing and Spotbill Duck.
5. Pothamala hills is located at
(a) Kerala Tamil Nadu boarder
(b) Karnataka Goa boarder
(c) Maharashtra Gujarat boarder
(d) Odisha Andhra Pradesh boarder
Answer: a
Justification:
- Recently, new menhirs were found on the Pothamala hills on the Kerala-Tamil Nadu border.
- Pothamala hills houses hundreds of cobbled stone structures, pointing to the existence of a structured graveyard of a prehistoric civilisation dating back around 3,000 years. These menhirs are the largest-ever recorded Menhirs in Kerala. Menhirs are monolithic slabs that are erected above the ground and may be small or gigantic in height.
- Menhirs are endemic to certain regions only and are a feature of megalithic culture.
